<P>PROBLEM TO BE SOLVED: To provide a one-touch coupling allowing a coupling body to receive a bending load via a sleeve member, even if an abrupt bending is applied to a pipe, eliminating a load from applying to the pipe itself, and retaining the function of a water stop member. <P>SOLUTION: This one-touch coupling comprises the coupling body 31, a lock member 38 provided inside the coupling body and having a lock claw 37 to be locked with the external surface of a pipe 10 to be connected, and the sleeve member 21 mounted on the end of the pipe and connected with the pipe locked to the lock claw of the lock member and prevented from being pulled out by inserted into the coupling body. The sleeve member is characterized in having a long cylinder part 23 to be inserted into the pipe, a short cylinder part 24 to be fitted with the inner circumferential surface in the inner part of the coupling body in the connection to the coupling body, and the water stop member 26, at least, in the short cylinder part. <P>COPYRIGHT: (C)2003,JPO |
